Final answer:
The correct factored form of 18F - 45 using the Greatest Common Factor is 9(2F - 5).
Step-by-step explanation:
To factor the expression 18F - 45 using the Greatest Common Factor (GCF), we need to find the highest number that divides both 18 and 45 without a remainder. The GCF of 18 and 45 is 9. So, we can factor out 9 from both terms.
Step-by-step, the factoring looks like this:
- Identify the GCF of 18 and 45, which is 9.
- Divide both terms by 9: 18F becomes 2F and -45 becomes -5.
- Write the factored form as 9(2F - 5).
The correct factored form is b) 9(2F - 5).
